Hallmark Stamp .750 For Ring Stamping Machine & Jewelry Marking Pliers

The .750 Hallmark Stamp is designed for use with both ring stamping machines and jewelry marking pliers, securing firmly in place via a set-screw for consistent, repeatable impressions. The stamp face is slightly radiused to conform to the interior curve of ring shanks, ensuring clean, legible marks on rounded surfaces. Impression height is 0.80 mm unless otherwise noted.

In European hallmarking standards, .750 denotes 18k gold — the designation indicating 750 parts per thousand pure gold. This stamp allows jewelers and metalsmiths to apply the appropriate fineness mark directly to finished or in-progress ring work with precision and efficiency.
